Eaton EHD2045 - 45 A, 480 V, 2-Pole Bolt-On Circuit Breaker | AmpState

Introducing the Eaton EHD2045 — a 45A, 480V, 2-pole bolt-on molded case circuit breaker designed to deliver dependable branch circuit protection in panelboards and load centers.

Engineered for secure, long-lasting performance in a variety of settings, this unit brings together rugged mounting, precise protection, and seamless compatibility.

• Secure bolt-on mounting: provides a rigid, vibration-resistant bus connection that stays tight in demanding environments, reducing the risk of loose connections and intermittent trips.
• Thermal-magnetic trip unit: combines thermal overload protection with magnetic short-circuit protection for stable, repeatable response across temperature changes and load conditions.
• OEM panel compatibility: specifically designed to fit and function with matching OEM loadcenters and panelboards, simplifying replacements and upgrades.
• 2-pole design for simultaneous protection: protects both conductors together, ensuring coordinated disconnection on any fault and improving overall safety.
• Broad applicability: suitable for residential, commercial, and light industrial applications where 480V circuits require reliable protection at 45A.

This breaker is ideal for electricians and facilities managers who need a trusted, drop-in replacement in Eaton-enabled or compatible panel systems. Use it to upgrade existing distributions when you’re upgrading circuits to a 45-amp load or when building compact, safe, code-compliant electrical closets and panelboards.
